Strange brown dwarf 'The Accident' hints at possible treasure trove of cosmic anomalies

The article reports that this likely brown dwarf is some 10 to 13 billion years old and states, "Observations of The Accident also show the object contains low levels of methane, compared to most other brown dwarfs. This characteristic further supports the idea that the object formed soon after the Milky Way formed about 13.6 billion years ago, at which point the galaxy was composed almost entirely of hydrogen and helium, and lacking the carbon needed to create methane, according to the statement. "

My observation. The NASA ADS Abstract, The Enigmatic Brown Dwarf WISEA J153429.75-104303.3 (a.k.a. "The Accident"), https://ui.adsabs.harvard.edu/abs/2021ApJ...915L...6K/abstract, July 2021. The 8-page arXiv paper, https://arxiv.org/pdf/2106.13408.pdf, 28-June-2021. This possible brown dwarf is said to be 10 to 13 billion years old in the phys.org report. The brown dwarf is moving at some 207 km/s so in 10^5 years, could travel 69 light-years. It is currently about 53 light-years from earth so extrapolating the brown dwarf age back 10 or 13 billion years old, opens an immense distance and orbital revolutions in the Milky Way galaxy since its origin. Difficult to confirm this galaxy travel history since its origin. The phys.org report says the Milky Way galaxy formed some 13.6 billion years ago as well as other reports. Using the cosmology calculators and defaults, this shows the universe angular diameter size ~ 280 million light years diameter when our galaxy formed compared to present size, about 93 billion light years diameter where CMBR z ~ 1100 today. The universe diameter expands by some 335x larger in the model explanation for the age of this brown dwarf observed within 53 light years of earth today and the age of the Milky Way used when our galaxy first formed in the universe. Quite a bit of interpretation and extrapolation in the explanation for observing this brown dwarf and fitting it into the stellar evolution model.
